The Company continues to review the metallurgical results to date in an effort to determine next steps for future studies intended to advance the Pinguino asset. Please visit the Company's website at www.argentexmining.com for full disclosure on the metallurgical studies.

About Pinguino

Argentex's 10,000-hectare advanced silver and gold exploration Pinguino project is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. The Deseado Massif is an active region of mining with four precious metal mines currently in production, and includes multiple active advanced and early stage exploration projects.

The Pinguino system has grown to 70+ individual veins, with a combined strike length approaching approx. 113 line-kilometers. The Pinguino project is unique within the Deseado Massif region of Santa Cruz province in that it contains two different and spatially distinct types of mineralization, one precious metal and the other sulphide-rich polymetallic. The Company continues to evaluate the geological model of sulphide-enriched potentially mineralized intrusives at depth, forming the probable source for the polymetallic veins exposed on surface.

Pinguino is easily accessible, situated approximately 400 meters above sea level in low-relief topography. An existing system of all-weather roads provides year-round access to the property.

Technical discussions related to the metallurgical studies has been reviewed and approved by Mr. Robert Tucker, P.Eng. Mr. Tucker supervised and interpreted results of the metallurgical test work and is a "Qualified Person" as defined under the terms of National Instrument 43-101. Metallurgical testing was carried out by ALS-G&T Metallurgical Labs in Kamloops, BC and ALS-Ammtec Metallurgy in Perth Australia.

All other technical content of this press release has been reviewed and approved by Mr. J. David Williams, P.Eng., an independent "Qualified Person" as defined by NI 43-101.

Statements in this news release that are not historical facts are forward-looking statements that are subject to risks and uncertainties. Words such as "expects", "intends", "plans", "may", "could", "should", "anticipates", "likely", "believes" and words of similar import also identify forward-looking statements. Forward-looking statements in this news release include the Company's belief, based on the fact that silver and gold were still leaching when the tests were terminated, that recoveries may increase with longer leaching period, its anticipation that future process optimization studies will improve recovery efficiencies and cost reduction benefits; Its expectation that with further work, the variables in the flotation testing could be optimized with respect to both improved recoveries and lower grinding requirements ;its understanding that, because both silver and gold were still leaching when the tests were terminated, recoveries may increase with longer leaching periods; its anticipation that mineralogical work currently underway to identify the high grade silver mineral in this material and future testing will involve optimization of recoveries and reagent requirements related to its presence; that future work will use the new resource estimate to determine representative samples and that this will allow metallurgical test work to be done in a manner that allows various process options to be evaluated in terms of recoveries and costs. Actual results may differ materially from those currently anticipated due to a number of factors beyond the Company's control. These risks and uncertainties include, among other things, the availability of the Company's consultants and risks that are inherent in Argentex's operations including the risks that the Company may not find any minerals in commercially feasible quantity or raise enough money to fund its exploration plans. These and other risks are described in the Company's Annual Information Form and other public disclosure documents filed on the SEDAR website maintained by the Canadian Securities Administrators and the EDGAR website maintained by the Securities and Exchange Commission.
